ful Improvements in 'Car-Trucks, of which l f the following is a seci-iication.

This invention ire ates to improvements inl car trucks, and the primaryobject fof `the same iswto provide an improved truck so constructed that`the motor maybe mounted directly Vthereon Without altering the presentor standard construction of-car. body.

A Vfurther objectl is to provide :an im' proved 'truck upon whichtheinotor may be mountedlifna horizontal position to permit` a motorvofthe requiredcapacitytobeused.

A further object is l to provide. an im'-A pioved combined en ine-frameand bolster. A further object 1s `to provide improved means forsupporting the brake'rigging by i the motor frame.

LA fuitherobjectfis 4to provide improved means vv'for' 'coolingtheengine frame and the .-25

l' 9 of' `the drawings, i and' said j hangers," "are -held 'againstvaccidental `displacement by means of suitable 'Cotter pins 78 whichpass' -tlironghfthe extremities of. the' pins' 70 be- 130 enana lVE-yond tlieiffliangersf The lhangersare'piovided "the ordinary brakeshoes '74 vwhich are vadapted toengage the Yperip'liries of thesmpporting wheels.23, and the re-` .'spec'tive hangers are` connectedfby crossv ,beams 7 5, 7 6. Amember 7 7 is provided withv lanaperture-78 extending therethrough, and:

a countersunk portion 79 located adjacentv v one ,face Athereof andIextending through the rovided aperture `78 isa pin- 8Qwhich is with'aheaded portion 81 adapte to rest `within the countersunh portion 79, andsaid pin 80- is'of such avlengthas to extend lfor vsome distancebeyondt'he member? 8. This member 78 is adapted to be secured 'toatinished face or projectingportion. 82 on the e vine frame in anydesired orsuitable manp ner, preferably by means of vbolts or rivetsandewhen in 'position the pin or bolt 8() is 'held aga-inst accidentaldisplacement by means of theupper portion ofthe head -81 thereof.engaging the botto'inofthe engine 1 frame. This pin or bolt 80 serves asa 4support for a lever 84, which lis pivotally supis held againstvdisplacement by means of al" .Cotter pin 86,l .which passestransversely ported4 thereby," as 'shown more clearly in Figs. 2 and 9of the drawings, and said lever;

through the extremityof the'pin or bolt-'8O `and below a. Suitablewasher 87 which is disposed beneath the lever 8 4. Suitable oo nnectingbars or `links 88 arevivotally-connected respectively by yone en beams75, 76,'and`by their other end to the lever SI1- on each side of thepoint of,piv otal supportthereof, and'serve as means for applying thebrake shoes v74: to the periph-` eries of the respective wheels 'when'the lever 84 is rocked by means ofthe lever 89, which is'connected tothe lever 84 through the medium ,of the connecting link 90 shown moreclearly in Fig. 9 of the drawings; i

. It will thus be i seen that with this improved construction, the motoris mounted directly upon the truck, and thetruck is `so' constructedthat the engine or motor may he `placed horizontallythereon in order topermit a motor of the required capacity to "be used-, The truck being ofthe standard size, may be placed under the car sill 9], of

` the car body without altering or changing the present construction kofthe car, and when in j position, the Imotor willbe supported by theAtruck below the lcar sill, thereby permitting an improvedtruckconstructed in accordance fivith th principles of this invention tobe applied to any of the present construction ofcars, -w
